Question

question 10 of 10
when describing the difference between endocrine and exocrine glands, which of the following
would the instructor include as characteristic of endocrine glands?

• the secreted hormones act like target cells.
• the secretions are released directly into the blood stream.
• the glands play a minor role in maintaining homeostasis.
• the glands contain ducts that produce the hormones.

Explanation:

To determine the characteristic of endocrine glands:

• Analyze Option 1: Hormones act on target cells, not "like" target cells. Eliminate.
• Analyze Option 2: Endocrine glands secrete hormones directly into the bloodstream (no ducts). This matches.
• Analyze Option 3: Endocrine glands play a major role in homeostasis (e.g., via hormones like insulin, cortisol). Eliminate.
• Analyze Option 4: Endocrine glands are ductless; exocrine glands have ducts. Eliminate.

Answer:

B. The secretions are released directly into the blood stream.
